I have a G4 with a 40GH Hard Drive. I am running 9.2.2 and want to upgrade to Panther 10.3. Can someone run me through the steps of partitioning my HD...and how much should I allocate to 9.2.2 vs. 10.3? Do I just make two partitions? Do I do this before installing OS X, or while I'm doing it? Any help would be greatly appreciated. Are there any disadvantes to having a partitioned drive?
